Fossil fuels
• combustible materials made from fossilised remains
• non-renewable
• contain hydro-carbonscoaloilnatural gas

Coal
• extracted from the ground
![Page 5: ENERGY FOSSIL FUELS What are fossil fuels? Spatial distribution and consumption of oil, coal and natural gas Change of use of fossil fuels through history.](https://reader035.fdocuments.in/reader035/viewer/2022062423/56649e025503460f94aed2d6/html5/thumbnails/5.jpg)
Why is coal so important?
• the most common source of electricity world-wide
• the safest fossil fuel to transport, store and use
• abundant coal reserves coal users are guaranteed security of supply at competitive prices electricity supplies for industrial and domestic use are assured

Coal’s role in the world
• Over 23% of primary energy needs worldwide are met by coal.
• 39% of global electricity is generated from coal • 66% of global steel production depends on coal • Spending is increasing on technology research
and development programmes to improve thermal efficiency and reduce GHG and other emissions.

Uses of coal
• solid fuel to produce heat through combustion produces CO2 and SO2 environmental damage (e.g. acid rain, global warming)
• electricity generation• can be converted into liquid
fuels like gasoline or diesel• steel and cement
manufacture

Uses of oil
• fuel (e.g. transport, heating)
• plastics
• lubricants in engines
• roofing tiles
• e.g. fertilizers, medicines – indirect need of oil
World consumption: roughly 77 million barrels of oil a day

Natural gas
• a gas produced by the anaerobic decay of organic material
• usually found in oil fields and natural gas fields, but is also generated in swamps and marshes in landfill sites, and during digestion in animals.
• commercially produced from oil fields and natural gas fields
![Page 19: ENERGY FOSSIL FUELS What are fossil fuels? Spatial distribution and consumption of oil, coal and natural gas Change of use of fossil fuels through history.](https://reader035.fdocuments.in/reader035/viewer/2022062423/56649e025503460f94aed2d6/html5/thumbnails/19.jpg)
Uses• Power generation• gas turbines and steam turbines • natural gas produces less greenhouse gases. For an equivalent
amount of heat, burning natural gas produces about 30% less CO2 than burning oil and about 45% less than burning coal
• Combined cycle power generation using natural gas is thus the cleanest source of power available using fossil fuels
• Natural gas vehicles• Compressed natural gas (and LPG) is used as a clean alternative to
other automobile fuels• countries with the largest number of natural gas vehicles: Argentina,
Brazil, Pakistan, Italy, and India
• Domestic use - cooking and heating• Fertilizer - a major feedstock for the production of ammonia

![Page 32: ENERGY FOSSIL FUELS What are fossil fuels? Spatial distribution and consumption of oil, coal and natural gas Change of use of fossil fuels through history.](https://reader035.fdocuments.in/reader035/viewer/2022062423/56649e025503460f94aed2d6/html5/thumbnails/32.jpg)
What will happen in the coming century?
• Coal is most likely to remain for longer. 500 billion tones of coal, about 200 years’ worth, remain underground. ( figure 2)
• Oil and gas are the most likely to run out within the next century.
• Over the last 25 years, various predictions have been made about the supply of crude oil. According to these figures, we should have run out of oil by now!
• However, more oil’s fields are discovering by the time!
